An auto loan underwriter analyzes a vehicle loan application and decides to approve or deny financing. In this career, your duties include collecting financial data from the person seeking a vehicle loan, either face-to-face or over the phone. Your responsibilities can also include negotiating with the customer about down payments, interest rates, and other issues. Occasionally, you help a customer find a loan that fits their needs and financial situation. You document your research and risk assessment findings and ensure that the lending process meets legal requirements.
